What is Laminar?
Laminar is the comprehensive open-source platform designed for developers building AI agents. It addresses the critical challenges of monitoring, debugging, and improving agent performance in production, empowering your team to deliver dependable AI solutions with confidence.
Key Features
📊 Real-time AI Agent Observability: Gain immediate insights into your agent's behavior. Laminar provides real-time tracing of long-running agents, automatic error capture, and detailed visibility into tool calls and structured outputs, ensuring you can debug issues as they happen.
🧪 Powerful Evaluation Framework: Streamline your agent performance improvements. With a zero-boilerplate evaluation SDK, you can quickly write and run sophisticated evaluations, iterate on prompts in an interactive playground, and catch regressions before they impact users.
🔍 SQL-Powered Data Analysis: Unlock deep insights from your agent data. Laminar offers a built-in SQL editor to query all traces, evaluations, datasets, and events, allowing you to create custom dashboards and transform queries into evaluation datasets efficiently.
🌐 Extensive Integrations & SDK: Get started quickly with broad compatibility. Laminar's best-in-class SDK enables easy tracing, and it automatically integrates with popular LLM frameworks and SDKs like LangGraph, CrewAI, OpenAI, Anthropic, and many more, often with just a two-minute setup.
Use Cases
Proactive Debugging: Immediately identify and resolve issues in complex, long-running AI agents by observing real-time traces and automatically captured errors, preventing extended downtime or poor user experiences.
Rapid Iteration & Improvement: Accelerate your development cycle by quickly testing new prompts and models in the Playground, then validating performance improvements and catching regressions with comparative evaluation runs before deployment.
Custom Performance Monitoring: Tailor your monitoring strategy by using SQL queries to define and track custom metrics relevant to your agent's specific goals, visualizing these insights through personalized dashboards.
Why Choose Laminar?
